Dec 11, 2013 - Many patients with myeloproliferative neoplasms without mutations in the Janus kinase 2 gene (JAK2) or in the thrombopoietin receptor gene (MPL) have mutations in the CALR gene encoding calreticulin, according to two studies published online Dec. 10 in the New England Journal of Medicine. The research was published to coincide with presentation at the annual meeting of the American Society of Hematology, held from Dec. 7 to 10 in New Orleans.
